报告摘要/Abstract:

Neutron and x-ray scattering techniques are important tools for studying the structure and dynamics of high-temperature melts. However, these studies are often restricted by the high-temperature limits of standard furnaces and by possible contamination of the sample by the container. These problems can be overcome by using levitation techniques, which make it feasible also to avoid heterogeneous nucleation, giving the possibility to undercool hot liquids down to several hundred degrees below their equilibrium freezing point. Various containerless methods have been developed and their integration at neutron sources and x-ray synchrotrons provides powerful tools to study the structure and dynamics of molten materials. This talk presents an overview of the levitation techniques routinely combined with neutron and x-ray techniques as well as experimental results obtained on various metallic melts.
